Objective To explore the value of CR in the diagnosis of breast cancer in young women.Methods The relationshipbetween X-ray features of 50 cases of breast cancer in young women and pathology were analysed retrospectively.Results Infiltratinglobular carcinoma was in 26 cases,and infiltrating ductal carcinoma was in 24 cases.Mass shadows was in 13 cases,pure calcification 7cases,structure disorder 5 cases,patches shadows 16 cases,patches shadows with calcification 4 cases and mass with calcification 5 cases.Conclusion Mammography is still the best method for breast cancer in young women.

Objective To analyze radiological features of rare tumor of breast.Methods To analyze retrospectively radiological features of 11 cases with rare tumor, all cases were confirmed by operation or pathology. Results Among the 11 cases ,1 case was non Hodgkin lymphoma(NHL). 1 case was malignant pleomorphic adenoma. 1 case was primary squamous cell carcinoma of breast. 1 case was osteosarcoma.2 cases were lobate cystadenosarcoma. 5 cases were hamartomas.Osteosarcoma shows bone tissues in the mass. Malignant pleomorphic adenoma shows more big mass with leaning-edge and abnormal vessel.Lobate cystadenosarcoma is a low-degree malignant tumor with long history, shows big mass, cleaning-edge and big calcification in it, there was a vitellary membracnce around the mass, usually no metastasis to armpit .Hamartoma’s density is highly uneven, the area of high density likes island. Primary squamous cell carcinoma of breast and NHL have no specific X-ray features.Conclusion Rare breast tumors have no specific radiological featare.Qualitative diagnosis needs sythetical analysis.

Objective To probe the X-ray imaging features and clinical manifestations of some rare diseases in male breast.Methods The data of 12 patients with some rare diseases in male breast were collected.The X-ray manifestations and clinical features of the diseases were analyzed.Results The postoperative pathology showed the lipogranuloma in 1 patient,plasma cell mastitis in 2,secondary infection of epidermal cyst in 1,intraductal papilloma in 1,breast cancer in 6 (invasive ductal carcinoma in 4,poor-differentiated adenocarcinoma in 1,and mucinous carcinoma in 1),and breast lymphoma in 1.The digital mammography showed the intramammary solitary masses in 1 1 and multiple ones in 1.10 masses were located at the rear of the areola,and other 2 were opposite.Unclear edge of the lesion was found in 9,spiculation in 1,lobulation in 1,and micro-calcification in 1.Nipple retraction and areola skin thickening in 10 and enlarged axillary lymph node in 1 were also found.The total accurate rate of X-ray diagnosis was 41% (5/12),while that of breast cancer was 83.3%.The total misdiagnosis rate was 59% (7/12),and that of benign lesion was 80% (4/5).Conclusion The diseases in male breast are rare and various,and the X-ray and clinical manifestations are not specific.

Objective To probe the blood supply of liver metastasis by celiac artery,proper hepatic artery DSA.portal vein perfusion CT during superior mesenteric arterial poaography(PCTAP).Methods One hundred patients with liver metastases were examined prospectively by plain CT scan,multiphase enhanced CT scan,celiac arteriography and proper hepatic artefiography.Of them,56 patients were examined by PCTAP.All primary lesions wero confirmed by operation and(or)pathology examination.In order to investigate the blood supply of metastasis lesions.the software of Photoshop Was used to obtain the time-attenuation cugves(TDC)of tumor center,tumor edge,portal vein and normal liver parenchyma adjacent to the tumor to talculate liver perfusion for DSA image analysis,while a deconvolution model from CT perfusion software Was designed for the dual blood supply.Results DSA findings:TDC of proper hepatic arteriography showed:the mean peak concentration(K value)in tumor centers was(67±12)%,and it was(76±15)%for peritumor tissue,(51±10)%in normal liver parenchyma.TDC of celiac arteriogaphy showed that the contrast concentration of tumor centers and tumor edge increased fast in early stage.then maintained a slight upward plateau,in the meanwhile,the contrast concentration of normal liver parenchyma kept increasing slowly.PCTAP findings:tumors exhibited no enhancement during 30 s continued scans.Conciusion The blood supply of liver metastasis mainly comes from hepatic artery,but barely from portal vein.
